Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4222CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 42.2 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Variations in height (seated maximum) and exact dimensional tolerances remain within acceptable mechanical compatibility for standard PCB assembly processes. Packaging format differences (Tape & Reel vs. bulk) do not affect electrical or functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production Status):

CR1206-FX-4222ELF (Bourns Inc.) is recommended as the first substitute option. This part maintains active product status with 23,681 pieces in inventory. It meets all electrical and mechanical specifications with moisture-resistant thick film composition and ROHS3 compliance.

CRCW120642K2FKEA (Vishay Dale) is recommended for applications requiring automotive-grade qualification. This part carries AEC-Q200 certification, active product status, and 15,437 pieces in inventory. The seated height maximum of 0.024" (0.60mm) represents the most compact profile among available substitutes.

RC1206FR-0742K2L (YAGEO) is recommended as an alternative with active product status and 22,686 pieces in inventory. This part provides moisture-resistant thick film composition with dimensions of 0.122" L x 0.063" W.

Secondary Selection (Legacy Status):

ERJ-8ENF4222V (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically and mechanically equivalent with AEC-Q200 automotive qualification and 36,366 pieces in inventory, this part should be reserved for legacy system maintenance or replacement applications only.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4222ELF directly replace RCS3216F4222CS on existing PCBs?

A: Yes. Both parts share identical electrical specifications (42.2 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and 1206 package footprint. The maximum seated height difference (0.030" vs. 0.026") remains within standard PCB assembly tolerances and does not affect mechanical fit or electrical performance.

Q: What is the difference between the Samsung RCS3216F4222CS and Vishay CRCW120642K2FKEA?

A: Both parts are electrically identical. The primary difference is that CRCW120642K2FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The Vishay part also has a lower seated height maximum (0.024" vs. 0.026"). Samsung's RCS3216F4222CS includes anti-sulfur properties in addition to moisture resistance.

Q: Why is ERJ-8ENF4222V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While the part remains functionally equivalent and available in inventory (36,366 pieces), it should not be selected for new circuit designs. Use this part only for replacement or maintenance of existing systems already using this component.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Does packaging format (Tape & Reel vs. bulk) affect electrical equivalence?

A: No. Packaging format affects only logistics, storage, and assembly handling. All substitute parts listed are available in Tape & Reel (TR) packaging. Electrical performance, mechanical fit, and functional characteristics remain identical regardless of packaging format.

Q: Which substitute part has the smallest physical footprint?

A: CRCW120642K2FKEA (Vishay Dale) has the lowest seated height maximum at 0.024" (0.60mm), compared to 0.026" (0.66mm) for the original RCS3216F4222CS. This difference is negligible for standard PCB assembly applications.
